Cardiovascular magnetic resonance demonstration of the spectrum of morphological phenotypes and patterns of myocardial scarring in Anderson-Fabry disease.

Background: Although it is known that Anderson-Fabry Disease (AFD) can mimic the morphologic manifestations of hypertrophic cardiomyopathy (HCM) on echocardiography, there is a lack of cardiovascular magnetic resonance (CMR) literature on this. There is limited information in the published literature on the distribution of myocardial fibrosis in patients with AFD, with scar reported principally in the basal inferolateral midwall.

Methods: All patients with confirmed AFD undergoing CMR at our center were included.

Tracking and Resolving CT Dose Metric Outliers Using Root-Cause Analysis.

Purpose: The aim of this study was to examine the frequency and type of outlier dose metrics for three common CT examination types on the basis of a root-cause analysis (RCA) approach.

Methods: Institutional review board approval was obtained for this retrospective observational study. The requirement to obtain informed consent was waived.

Left-sided patent ductus arteriosus in a right-sided aortic arch.

We present a 31-year-old female with repaired tetralogy of Fallot (TOF) and right-sided aortic arch (RAA) with left-sided patent ductus arteriosus (PDA) originating from the left brachiocephalic artery. This is a rare finding but most common site for a PDA in TOF and a RAA. To the best of our knowledge, this is the first demonstration of this rare finding on MRI in the literature.

Bilateral mobile thoracolithiasis.

Thoracolithiasis is the presence of one or more freely mobile pleural stones (with or without calcification) in the pleural space. They occur with a reported incidence of less than 0.1% and are benign and do not require intervention.

Deep basal inferoseptal crypts occur more commonly in patients with hypertrophic cardiomyopathy due to disease-causing myofilament mutations.

Purpose: To determine the relationship between deep basal inferoseptal crypts and disease-causing gene mutations in hypertrophic cardiomyopathy (HCM).

Materials And Methods: Institutional research and ethics board approval was obtained for this retrospective study, and the requirement to obtain informed consent was waived. Two readers, who were blinded to genetic status, independently assessed cardiac magnetic resonance (MR) images obtained in 300 consecutive unrelated genetically tested patients with HCM.
